有做检测的朋友吗?关于REACH里Phthalate的限量值有疑问,3P(BBP, DBP, DEHP)里的要求是这么写的“Shall not be used as substances or as constituents of preparations, at concentrations higher than 0,1 % by mass of the plasticised material, in toys and childcare articles” ,假如现在有一只鞋子的塑料大底要做REACH的3P,你们是怎么做的?我的做法是把鞋子的所有plasticised material拆出来称重,然后塑料大底和所有plasticised material分别称重,然后测塑料大底的3P含量,最终的concentrations 为:试验测得的3P含量x塑料大底重量/所有plasticised material重量,不知我这样搞对不对?有些客人是除整只鞋子重量的。
